Blind trading and lucky trading are not strategies in trading.
But don't you think there are two types of loss? The first is the losses that arise when the market does the less likely thing of the two things it could have done. So, if your analysis is correct 99% of the time and you always follow the same process, when 1% of your trades are losses, this is not down to a mistake or bad luck, it was inevitable.
The other type of loss is down to a mistake. Perhaps you forgot a step in your analysis or forgot to enter a stop-loss. Perhaps you thought NFPR's would be stronger and they were weaker. Perhaps you bought when you meant to sell. These are the traders's mistakes. They are not bad luck. There is no such thing as luck in trading.
